Contents:
Abstract -- Acknowledgements -- Table of Contents -- I. Introduction -- II. Distribution and Abundance of Benthos in a Lake Receiving Heated Effluent -- III. Electron Microscopic Examination of the Frontal Ganglion of Larvae of Chaoborus punctipennis (Diptera) Through the Annual Cycle and After Thermal Stress -- IV. Conclusions.
Abstract: This final report presents ecological and ultrastructural data on selected macroinvertebrates from Lake Keowee which receives heated effluent from three nuclear reactors. The ecological data shows the effects of depth, station, location and season on density, diversity and taxonomic composition of the collected benthos. Abundance and diversity of invertebrates was lower at the discharge canal and its surrounding areas than in the intake canal and control areas. Composition of the substrate and temperature of the environment have decided influences on the fauna of this relatively young lake. The subtle biological effects of a temperature change were determined by examining ultrastructurally the nerve cells of the frontal ganglion in Chaoborus punctipennis. There was a change in the density of nuclear pores and size of the endoplasmic reticulum cisternae in animals exposed to 30°C for three hours and only a change in nuclear pore density in insects held at 25°C for the same time period.
